China Mobile and ZTE Complete First Wireless Network Digital Twin Application for XR Service


China Mobile and ZTE have completed the first wireless network digital twin application for Extended Reality (XR) service in Jiangxi. The test results show the twinning precision of XR has reached over 90% in areas such as parks and squares. This marks a key step in applying digital twin technology to wireless networks. It also lays a solid foundation for XR service experience guarantee and network policy optimisation.

The development of 5G has witnessed the continuous introduction of new applications. It has also seen increasingly diversified terminal types and capabilities and multi-band multi-mode collaborative networking becoming prevalent. In such a complex network, efficiently optimising network configuration and accurately guaranteeing user experience has become pivotal.

The wireless network digital twin can implement digital modeling. It can also build dynamic simulation for base stations, wireless channels, terminals, core networks and services based on COTS servers. It also builds high-precision digital twins for physical networks. Through the mutual data interaction and performance verification with physical network, the wireless network digital twin can help operators optimise network resource allocation, accurately guarantee user experience and implement trial-and-error innovation with low cost.

High-precision service modeling is the key to unleashing the potential capabilities of digital twin applications. In the recent XR application in Jiangxi, testing engineers conducted XR tests in more than 70 locations under the coverage of 130 5G base stations in the physical network. ZTE’s high-fidelity wireless network digital twin platform also performed network and application performance twinning of the same XR service. By comparing the differences of the key performance indicators, the twinning precision can be calculated. The results show that the twinning precision of XR application has reached over 90% in areas such as parks and squares. (Click the link to explore more details:

XR is the key technology that opens the door to the metaverse. And it is coming under the catalysis of 5G. China Mobile and ZTE will further cooperate to continue the exploration of XR experience guarantee and policy optimisation based on the wireless network digital twin. This will empower more 5G new services such as streaming and cloud gaming.

In the future, the application of wireless network digital twins will expand to more fields, like network planning and optimization. The result will be a highly autonomous and intelligent network.
